Background & Data

Description of Data Collection

The data collected in the calibration experiment consisted of a known load,
applied to the load cell, and the corresponding deflection of the cell from
its nominal position. Forty measurements were made over a range of loads from
150,000 to 3,000,000 units. The data were collected in two sets in order of
increasing load. The systematic run order makes it difficult to determine
whether or not there was any drift in the load cell or measuring equipment
over time. Assuming there is no drift, however, the experiment should provide
a good description of the relationship between the load applied to the cell and
its response.
